Available in PDF, EPUB and Kindle. Book excerpt: This report is a view of irrigation technologies for smallholders in the context of improving rural livelihoods, especially in regard to the prospects for sub-Saharan Africa. The role of traditional technologies is evaluated and modern water distribution technologies, such as sprinkler and trickle irrigation, are reviewed. A broad classification has been made based on climate and the traditional agricultural background of the local people, which links technology options to specific places--to agricultural regions and to countries.

Book excerpt: For decades now we have wasted and mismanaged the world?s water supplies. Today, 27 countries are short of water, a quarter of the world?s population has no safe water, 46 per cent have no proper sanitation and each year four million children die of water-borne diseases. As most of the world?s major river systems cross several national boundaries, the scope disputes and the threat to international security is becoming more and more real. In The Last Oasis, Sandra Postel examines the economic, ecological and political factors affecting fresh water supply. She confronts the issues of mismanagement and profligacy and analyses and dangers of confrontation, both between nations and between rural and urban users. She also emphasises that the technology and know-how for effective water husbandry does exist. With methods already in use, farmers could cut their demand for water by 40-90 per cent, and cities by one-third, without sacrificing economic output or quality of life. Investing in water efficiency, recycling and conservation help meet rising demands and stave off disaster. But the priority is a common recognition of the gravity of the position, and with that a widespread push for institutions to manage sustainable use of water.

Download or read book Productive Water Points in Dryland Areas written by Chris Lovell and published by Guidelines on Integrated Plann. This book was released on 2000 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lack of water is the limiting factor for many household and community- based activities for millions of people living in dryland areas. Rural water supply programs tend to focus on only two social aspects: improved access to domestic supply and improved sanitation. Less attention has been paid to how communities prefer to use water to develop their own livelihoods. This is due partly to the difficulties of abstracting sufficient reliable groundwater in dryland areas, and partly to a misunderstanding of why wells and boreholes fail, which leads to a general belief that abstraction should be limited to domestic supply to conserve the resource. When more water is available, not only are basic drinking and washing needs satisfied but also other activities with a high economic value become feasible, such as small-scale irrigation, fruit orchards, livestock feedlots, small-scale dairy units, fish farming, brick-making, etc. Such diversification avoids over-reliance on rain-fed cropping of marginal lands. This book shows how research in southern Africa has shed light on why conventional wells and boreholes fail, on the potential of the groundwater resource to support production through improved siting and selection of more appropriate well designs, and on the positive impacts and some problems that can emerge at productive water points.
